Wrap-up and Quiz

Let's go over the main topics we covered in this chapter and test our knowledge.

We'll cover the following

Summary#

Kubernetes has become a standard tool for managing container workloads. Many companies rely on it to build and scale cloud-native applications, which power many of the products and services we use today. Although companies are adopting Kubernetes and reaping some of the benefits, developers aren’t interested in the low-level details of Kubernetes. They, therefore, want to focus on their code without worrying about the infrastructure bits running the application. Knative makes deploying, updating, autoscaling, and composing event-driven software easy.

You can learn more about Knative and the kn CLI at Knative dev.

Let’s review what we’ve learned in this chapter:

  • We learned how to install the Knative Serving component and deploy services to run on it.
  • We also learned how to deploy services and manage their configuration using the kn CLI.
